The Chelsea 645KJKX-4JL or 645KJKX4JL is a geared adapter PTO assembly designed to mount on a 6-bolt transmission opening. Its 45-degree downward angle moves the PTO away from chassis components, helping clear interference that a straight-mount unit cannot. The 645KJKX-4JL shares its input gear set with the Chelsea 442 Series, which simplifies parts sourcing and service for fleets already running 442 Series PTOs. Dimensions are 7.75 in. high by 10.75 in. wide by 10.75 in. long. Available from Pro Gear and Transmission. Call us to confirm proper fit for your transmission and application.
